if i cut out a 12-12 1/2 inch hole that would be to big right.....isnt 12 inches from end to end of the ring........also could i make a ring to go on the inside so the sub would sit flush to the box?


btw this is for 2 12in. Type X's

any help is apriciated........I AM A N00B at building boxes lol

you'll need a 9.1" diameter. 4.55" radius.

just becuase it is a 12" sub dont mean you'll need to make a sub cutout of 12". your sub will end up just sink in the hole.

like livinlife said a 12" sub doesn't need a 12" cut out. Easy way to flush mount subs is to use a double baffle. :)

radius is half diameter. So 9.1 / 2 = 4.55" :)

Dude... didnt you take math???!
Radius is half the circle Diam. is the full distance accross the circle....

so would i cut the first baffle out at 12inches? then the second one at 9.5?

Yeah, the first cutout is for the sub to mount in then the second baffle needs to go around the sub so it needs to be 12 inches. I would go a little bigger than 12 though, maybe 13 or so. That way you can get it out easier and move it around once you drop it in. ;)

its easier to cut, i suppose, with the radius then diameter... just use a thin cardboard paper and make two points, 4.55" radius in between, and DRAW!

^Like he said . But I usually oversize by a 1/4" just so the sub doesn't fight me :)

look at the pic of my W6 below...
the cut out diameter is how big you want to make the hole in your sub box from one side to the other. your owners manual should tell you how large to make this hole.
if you are going to use a compass to draw your circle divide the cut out diameter in half to get the radius.
to make your box flush mount you'll want to now measure the flush mount diameter so you can build another baffle to put on top of the regular baffle your box already has. most of the time the manual will also tell you this measurement. i usually cut them out so spec to give it a clean look but you can make it a little bigger than the woofer if you want.
lastly, if you really want a clean look measure the how deep the mounting flange is on your sub and get a piece of wood about the same thickness. so the sub doesnt stick out too much or it isnt sunk in too deep.
i think the alpine X and R subs have a pretty think rubber surround on their mounting flanges so another panel of 3/4 MDF should do the trick.

Jasper circle jig for the router. If you have a router I highly suggest one. Once you use it, you might end up smacking yourself for not getting it sooner :D :)

Like they said it's the grill. W6 doesn't have the surround covering everything like the W7 does. :)
